Hi Rachel - Welcome aboard! We are using this NING network as a place where educators can connect with each other (through answers to profile questions and the advanced Members search) and also as a way to connect educators with exemplary resources and professional development opportunities.
If you look on the Main page - you'll see MSP2 resources in the upper left hand box - we have resource guides where we have sifted and sorted and contextualized resources on topics important to middle school math and science teachers, an archive of all of our past webinars, the ability to search the MSP2 collection, and pages of teacher and student opportunities and grants. Our newest resource guide is about Teaching With Tradebooks and includes lessons for science AND math classes..
We have have on the right side of the page our two project blogs - Resources for Math and Science and Connecting News. We also RSS feed the Free Technology for Teachers, Teach Engineering, and Science and Technology NYT blog feeds.
You can see a list of all the MSP2 events and others that we think would be of interest to our audience under the Events tab. We have groups - including a book club - and lots of conversations! One of our most popular webinars was Reading Mathematics is Different - you can find the recording here - http://wiki.nsdl.org/index.php/MiddleSchoolPortal/Webinar_Archive.
Please don't hesitate to post a question or comment. We are always looking for feedback and new ideas for PD opportunities and people who would like to present. So glad you joined - Kim
